Molecular Dynamics Simulation Study on the Growth of Structure II Nitrogen Hydrate.

Crystal growth of N hydrate in a three-phase system consisting of N hydrate, liquid water, and gaseous N was performed by molecular dynamics simulation at 260 K. Pressure influence on hydrate growth was evaluated. The kinetic properties including the growth rates and cage occupancies of the newly formed hydrate and the diffusion coefficient and concentration of N molecules in liquid phase were measured.
